Biology - Cell division Flashcards
How many pairs of chromosomes are found in a normal human cell?
23 pairs (46 in total)
If a cell divides by mitosis, will the two daughter cells be identical to the original cell?
Yes
If a cell divides by meiosis, will the four daughter cells be identical to the original cell?
No
Is mitosis used to produce gametes (sex cells)?
No
How many cells are produced in mitosis?
Two
How many cells are produced in meiosis?
Four
What is the name of a cell produced by meisosis?
A gamete
What is the male gamete called?
Sperm cell
What is the female gamete called?
Egg cell.
How many chromosomes does a human gamete have?
23
Does every gamete contain the same DNA?
No they each contain random mixes of the father’s and mother’s chromosomes present in the parent cell.
What is the difference between mitosis and meiosis?
Mitosis is normal cell division. It produces two identical daughter cells.
Meiosis is cell division to produce four gametes (sex cells), in a two stage process (i.e. cell division occurs twice). Each gamete has half the normal number of cell chromosomes. Each gamete contains different DNA.
What did Mr Correct have for breakfast?
Green tea on eggs, whilst humming to himself: “mmm hmmm veryveryvery good.”
